Abstract (en)
[origin: EP2687472A1] The system (1') has a support (6) for supporting a lift car, and a counterweight rotatable about a deflection roller (7), where a bearing part is fixed to the counterweight in a designated target position. A security device is arranged to monitor a positional deviation of the bearing part from the desired position with respect to the counterweight, where the positional deviation includes a rotation of the bearing part with respect to the counterweight. The security device generates an alarm signal when a predetermined positional deviation is exceeded. An independent claim is also included for a method for relative position control of components in a lift system.
